This data presented herein are the research summary of
“mechanical behavior and durability performance of concrete
containing recycled concrete aggregate” (Paul, 2011) [1]. The
results reported in this article relate to an important parameter of
optimum content of recycle concrete aggregate (RCA) in production of new concrete for both structural and non-structural
applications. For the purpose of the research various types of
physical, mechanical and durability tests are performed for concrete made with different percentages of RCA. Therefore, this data
set can be a great help of the readers to understand the mechanism of RCA in relates to the concrete properties.

Four different percentages of volume fraction of recycle concrete aggregates are
replaced with natural aggregate in production of new structural concrete.
Various volume of recycle concrete aggregates are blended with natural aggregate
to investigate the physical, mechanical and durability properties

Value of the data
The influence of replacement of recycle concrete aggregate in production of new structural concrete is discussed here
This data set can also be used as a guideline for others to scrutinize the properties of recycle
concrete aggregate
The research data presented herein may be useful to manufacture different commercial elements
using recycle concrete aggregate
This data set may also encourage to recycle other wastes to minimize the dependency on natural
resources
1. Data
This dataset reported herein were obtained from the experimental studies conducted on the different percentages of recycle concrete aggregate (RCA) replacement in the concrete mix and relate them
to the influence of physical, mechanical and durability properties. The detailed of the dataset can also
be found in [1–3]. Additionally, the available data presented by other researchers [4–6] were used to
check the applicability of RCA in new concrete. A large number of cubes and cylinders (about 300) were
prepared to examine the aforementioned properties of RCA. Finally, the properties of concrete made
from RCA were compared with a reference concrete made with 100% natural aggregates (NA).
2. Experimental design, materials, and methods
The materials compositions for different RCA mixes used in the research are shown in Table 1.
The RCA was collected from the different sources of construction and demolition waste (C&DW) sites
in the Western Cape region of South Africa. Concrete was then made by replacing different percentages
(0%, 15%, 30%, 50% and 100%) of NA by RCA as they are assigned RCA0 to RCA100 in Table 1.

The physical properties of aggregates such as relative density of aggregates, aggregate crushing
value, flakiness index, and water absorption capacity were also measured and presented in Table 2. All
mixing was performed under laboratory conditions. Slump test to check the workability of the concretes was performed as per SANS 5862:2006 [7], and air content as per SANS 6252:2006 [8]. After
pouring concrete into the moulds, a vibration table was also used to ensure the compatibility of the
fresh concrete. The compressive and splitting tensile strength of hardened concrete was determined on
100 mm and 150 mm cube specimens according to SANS 5863:2006 [9] and SANS 6253:2006 [10],
respectively. Cylindrical specimens, 300 mm height × 150 mm diameter were used for evaluating the

investigated by means of chloride conductivity, water sorptivity and oxygen permeability index test
according to the guideline provided in [12,13]. Figs. 1–9 show the results when different percentages of
RCAs were replaced with NA in production of new concrete. Furthermore, based on available data on
RCA concrete the results were compared and details are discussed in [1,2].
